Abstract

CALCIUM carbonate can exist in three polymorphic forms, which in the order of their usual stabilities are calcite, aragonite and vaterite. Calcite is the most stable and the least soluble, and, therefore, the form in which calcium carbonate would be expected to precipitate from sea-water. It has been pointed out, however, that when carbon dioxide was removed from natural sea-water a precipitate of aragonite formed1. Since this discovery, much work has been performed which confirms the observation, and there are a number of suggestions as to the cause of this phenomenon2.
